Data Sheet
Transfer function (unbalanced - balanced):
Test matching network to unbal. 50 Ω / bal. 200 Ω (element values depend on PCB layout):
Cs1 = 5,6 || 1,8 pF
Lp2 = 120 || 270 nH
Lp3 = 150 || 390 nH
Cs4 = 5,6 pF
Cs5 = 6,8 pF
Note:
The specifications in this data sheet are valid for unbalanced - balanced operation. The test matching network is realized using M/A-COM 1:4 baluns TP103 with an insertion loss of 0,6 dB.
